I-GWDZ-, i-WDZA-, i-WDN-, i-WDZAN-: isizukulwane esisha sekhebula lamandla elinophahla lwe-polyolefin eline-smoke ephansi,
ubuthi obuphansi futhi awunayo i-halogen.
Ikhebula lochungechunge lwe-G-oxygen
Amanothi:
1. Ikhebula liyikhebula lethusi elilodwa eliyinhloko eline-voltage elinganisiwe engu-0.6/lkV (UO/U) ngaphandle kwenkomba ekhethekile.
2 Izintambo eziyinhloko ngezogesi ezisebenzisa isembozo esimnyama sokuvikela.
3. Ngaphandle kwesibonakaliso esikhethekile, zonke izintambo zegatsha zisebenzisa uhlobo olufanayo lwezintambo zikagesi njengezintambo eziyinhloko4. Uma ikhebula legatsha lidinga ucingo lwe-BV-500 olunezimpawu zombala (obomvu, oluhlaza okotshani, okhanyayo, oluhlaza okwesibhakabhaka.ophuzi/oluhlaza okotshani). Kufanele lucaciswe ngesikhathi soku-oda.
Izinga elijwayelekile lekhebula eliyinhloko kanye nekhebula legatsha lithatha i-XLPE noma i-PVC njengokushisa (lEC, GB, JIS,
Ikhebula lamandla kagesi eliphansi lifakwe i-PVC. Ikhebula elijwayelekile lesiqu liyikhebula elilodwa noma ngaphezulu eliyi-core twist (eliyi-core kuya kwe-core emihlanu yekhebula), ikhebula elilodwa eliyi-core lekhebula legatsha lingasebenzisa amandla ekhebula angashisi, angamelani nomlilo.
1. Ukumelana nokushisa >200MQ;
2. Ukuvikela i-InsulatiOn ukumelana ne-Voltage>3.5kV/5min;
3. Ukuqina komoya okuhle kakhulu kanye nekhwalithi yokuvikela amanzi. Uma ufaka amanzi ahlangene egatsheni, ukumelana kokuvikela okulinganiselwe phakathi kwamanzi kanye ne-cable core, kanye nemvamisa yamandla ukumelana ne-voltage kuhlangabezana nezidingo zezinto 1 no-2.
4. Ukumelana okuncane kokuxhumana kwegatsha. Inani lesilinganiso sokumelana kokuxhumana vs ukumelana nokungaguquguquki komugqa wegatsha olinganayo ubude lilingana noma lingaphansi kuka-1.2;
5. Amandla amakhulu e-joint short circuit. Izinga lokuguquguquka kwesilinganiso sokumelana nokuxhumana ngemva kwe-short circuit lilingana no-0.2;
6. Ngekhebula legatsha elilungisiwe elinohlobo lwe-ZR-YJV elivimbe ilangabi, isikhathi sokuzicisha sejakethi silingana noma ngaphansi kwamasekhondi angu-12 futhi sifinyelela ku-GB/T18380.3;
7. Ngaphandle kokunikezwa kwamandla esimweni esijwayelekile sokusebenza. Ikhebula lohlobo lokumelana nomlilo le-NH lingaphinde lisebenze ngokujwayelekile imizuzu engama-90 ngaphansi kwesimo sokusha futhi lihlangabezana ne-GB/T19216.21-2003;
8. Izinga lokushisa eliphezulu lokusebenza lethusi, umongo wekhebula lohlobo lwe-VV ungama-'C angu-70 kanti owekhebula lohlobo lwe-YJV ungama-90'C;
9. Inokumelana okuhle kakhulu nokugqwala. Ingavimbela ukuguguleka kukasawoti ongaphili, uwoyela, isisekelo, i-asidi, isixazululo se-organic nokunye;
10. Ikhebula legatsha elenziwe ngaphambili lohlobo lwe-YJV linokuqina okuhle kakhulu kwesihloko kanye nokumelana nokuguga;
11. Ikhebula legatsha elilungisiwe elihlanzekile lohlobo lwe-GWDZ-, WDZA-, WDNA-, WDZAN linezici ezifana nomusi ophansi, ophansi, ongewona i-halogen kanye nokumelana nomlilo njll.;
